Chapter 204 Advanced equipment is the key
"Master, please look..."
Song Yingxing pointed to the newly made grenade on the table: "According to the father's idea, Xiaguan worked with many craftsmen in Taipei and Western countries to develop and improve on our old-fashioned Sky Thunder, and developed this new type of Sky Thunder, which contains all the They are fifty tiny round steel balls. After exploding, the killing range can reach ten steps...
In addition, due to the instability of the new gunpowder, the current method of use is still the old-fashioned way of igniting the gunpowder, which can explode within five breaths after being ignited. "
"It's named 'Grenade', it can also be called a grenade," Chen Cao picked up a grenade and looked at it: "Did you succeed in getting the white phosphorus I gave you last time?"
"It's done," Song Yingxing nodded: "This thing can be used as a burning substance, but if it is ignited, it will be too dangerous."
"When you design a new type of grenade, you should design it in a way that does not require ignition. In addition, I talked about the rope grenade when I was in the academy last time. After this kind of grenade is produced, Temporarily suspending production, let people focus on designing drawstring grenades."
After Chen Cao talked about it several times, Song Yingxing felt very ashamed, so he handed over his hand and said that he would handle the matter well.
"How's the rifle thing going?"
Chen Cao walked around the workshop, then turned to look at Song Yingxing who was following behind. Song Yingxing quickly pulled Bi Maokang, who was even more advanced in firearms research, with him: "My lord, the completion is almost complete, but there is still room for bullets." gap."
Bi Maokang also replied: "After firing ten rounds of bullets, the original rifle's bolt puller will cause the barrel to explode due to insufficient friction and overheating inside the barrel. Therefore, the forging of the barrel is already the same as the forging method of the Westerners. We also chose the cold forging method, and added other mineral materials to the molten steel to form the alloy that the father-in-law said, and the effect was really good. After thirty rounds of bullets were fired, although the rifle barrel was hot, it still did not affect shooting."
"But sir, bullets are a big problem." Song Yingxing was a little confused: "The successful construction of machine tools allows us to make bullets as we like, but the current productivity of the compression drilling machine is simply not high enough. Under the premise that there is not enough copper material, Apart from testing guns, the workshop does not dare to produce excess bullets."
Copper rifle bullets are really expensive. Although the workshop's funds are sufficient, most of the energy now is spent on developing new artillery.
"Copper is a scarce mineral, and we don't have too many copper mines in the Ming Dynasty. Master, what do you think?"
Bi Maokang said it a bit euphemistically, but Chen Cao waved his hand: "You don't have to worry about the raw materials of the bullet. Just build it. According to the calculation method of the Westerners, the warhead must be made into a 7.62 mm rifle bullet, and the vernier caliper on the drill press must be The Thai and Western numbers are the main ones. If you can’t figure it out, let them do it.
Also, from now on, you have to make as many bullets for me as I get for you. The number of combat-ready bullets cannot be less than one million. "
"One million?" Bi Maokang shook his head repeatedly: "It's impossible, sir. Although we can make bullets, our production proficiency is not high. Even if we don't count the time for melting the copper material and finalizing it, the production of a bullet has gone from high to high. From the gunpowder machine tool to the drilling machine, it takes less than half an hour."
"Half an hour is too long," Chen Cao shook his head repeatedly. He knew very well about the production of bullets. Later generations were all mechanically automated, but now manual production is not enough time: "The more drilling machines and machine tools, the better, and water It’s the same as the hammer, but it’s designed to be driven by water, which can save a lot of time. In addition, you can’t forget about brushing the tung oil, otherwise the bullet will break..."
"I will obey..."
After Chen Cao finished arranging it in one breath, he took over from Song Yingxing the revolver gun that he had drawn and designed himself. The bright white gun body design was made of one of the few alloy stainless steels in their workshop, and it weighed a full one. Jin Sanliang: "Well, this is good. Do you have a custom outfit?"
"This is your first shot..." Bi Maokang said with a smile.
"This gun is named 'Da Ming 1626 Type Revolver Gun'. When new pistols are designed in the future, this gun can be exported." Chen Cao played with it for a while, and then loaded six bullets.
boom...
After a puff of smoke, the target in the distance was hit. Chen Cao nodded with satisfaction, then inserted the gun into the special holster, and then put the holster into his waist under his clothes.
"As for the rifle, it's called the Daming 1624 bolt-action rifle. Once the assembly is finalized, it will be produced as soon as possible. There can be no delay. Once it is produced, it will be packaged so that it will not be delayed when it is needed in the future."
After Chen Cao finished his instructions, he took his bodyguards to the Nanjing Military Academy not far from the workshop. He wanted to go to the academy to see their research results.
As soon as he stepped into the academy, Chen Cao heard a burst of cheers, followed by the sound of machines turning.
Nowadays, Cao Shiyun is a fifteen-year-old boy. He stands in front of the steam turbine that he has worked hard to develop over the past three years with high spirits, and then he keeps instructing his classmates in the research and development team to operate this rather large machine.
It wasn't until Chen Cao stood behind a group of students that Cao Shiyun, who was standing on the high platform and shoveling coal for the steam engine's boiler, saw Chen Cao wearing a ducal python robe.
In his excitement, Cao Shiyun ran down the high platform and clasped his fists towards Chen Cao: "My lord, you have lived up to your teachings. Our students have successfully developed a steam turbine."
The one-meter-diameter gear on the right side of the turbine is driving the crossbar below it. The round rotation of the crossbar causes the gears connected to the crossbar to rotate. The gear lever connected to the pinion drives two suspended wooden The wheel, that wheel spins so fast.
"Well, that's right. You also know to hang the wheel in the air during the test phase. If you use a wooden wheel, the weight of the wheel will be enough to bury the wheel into the soil."
Chen Cao nodded with satisfaction.
Cao Shiyun's face was covered with black soot, and so were his classmates. The steam engine was the first major project requested by Chen Cao, so the college allocated a lot of money to the entire class. The components of this turbine were all made by these students in the workshop. See in person how these craftsmen made it.
"The students discovered this. This wheel machine weighs three thousand kilograms. According to Western science, it weighs six tons. If we only use the technology of our Ming Dynasty to build carriages, the two load-bearing wheels must be at least three tons. .”
"You are very smart." Chen Cao touched Cao Shiyun's head: "But have you ever thought about it? Two wheels weigh three tons. Are there any other alternatives?"
"Yes," Cao Shiyun nodded confidently: "The student thought of lengthening the front of the car and placing six sets of wheels on the front. In this way, the weight is balanced and it can be safer in terms of traction."
At this moment, the turbine suddenly made a loud noise. It turned out that the boiler had exploded.
"It exploded again..."
Cao Shiyun turned his head and glanced at the turbine behind him, and then looked at Chen Cao very embarrassedly: "My lord, although the student has thought of this, after the success in the past year, no less than ten boilers have been blown up. The student really can't think of how. solve."
Chen Cao stepped forward and looked at the coal that had been destroyed by the hot water sprayed from the blown boiler, and then looked around again. He found that the turbine was missing one of the most important things.
"Cao Shiyun, I ask you, what does this turbine rely on to rotate?"
"Steam..." Cao Shiyun replied immediately.
"You think, your internal rotating turbine is only so big. In this closed space, steam is continuously generated, and the turbine can only use so much steam. So what should we do with the excess steam?"
This was an academic question. Cao Shiyun immediately began to think about it, and then said: "The excess should be let go... But sir, after letting it go, there will not be enough steam in the turbine, and once it is let go, the turbine will stop rotating. "
"You should have thought of this problem a long time ago..."
Chen Cao looked at a pull rope next to the boiler with interest: "So you made this pull rope."
"Yes," Cao Shiyun nodded: "It's just not used once. Every time three kilograms of charcoal are burned, the student will pull down the pull rope, open the lid of the boiler, release the steam, and then the turbine will stop."
Chen Cao laughed and said, "Why don't you make a pressure gauge? When the steam reaches a certain critical value, just pull down the rope and release the steam. Isn't this the best of both worlds?"
Cao Shiyun's eyes lit up. This smart student had already thought of something, but then he stopped thinking: "But when you pull the rope, the steam will be released."
"Idiot," Chen Cao cursed, "You install the spring made by the Firearms Department on the boiler lid. You pull it to release some steam. Once you release the force of the spring, the lid will return to its original state. You can put it in as much as you want. That's right? With the help of the pressure gauge, as long as it doesn't reach the critical value, you can do whatever you want..."
"That's right..." Cao Shiyun patted his forehead: "The student has been taught by the father-in-law and already knows what to do."
"It seems that Mr. Taixi taught you no nonsense, and you learned quite well. Come on, Cao Shiyun and his research team have made great achievements in developing steam turbines. Each of them will be given a scholarship of one thousand taels, and another fifty thousand taels of silver will be allocated to them. As funds for turbine improvement and development.”
"Thank you, Mr. Gong..."
According to the etiquette of the college, a group of students raised their hands and eyebrows to Chen Cao and gave a military salute to express their gratitude. Chen Cao returned the salute and then went to the firearms department of the college.
Lin Liangcai is now the leader of the firearms department, and he was the first to propose the alloy cold forging technology after being taught by Mr. Taixi.
"The student has met the father-in-law..."
A teacher had already told them the news about Chen Cao in the Steam Department, so Lin Liangcai couldn't wait to show off his research results in the past three years.
"Actually, we are only limited to the manufacturing technology of machines. If we increase investment in industry, I believe we will be more advanced than the Europeans in forging technology..." Chen Cao said noncommittally.
